Ambiguous keyboards can be used instead of scan matrices in Scanning Systems in order to increase the text entry rate. We present a novel alternative to assigning letters to keys by taking into consideration the shapes of lowercase letters in order to create simple layouts, leading to families of keyboards with 2, 3 and 4 keys. We have chosen the best 3-key layout using a single switch scanning system and a word level disambiguation algorithm with a 10,911 word dictionary and we have tested it. We predict 16.6 wpm for an expert user with a 0.5 second scan period. © 2010 Springer-Verlag Berlin Heidelberg.
